Flew mine this morning after the fixes, and it flew perfect!!! Thanks again for the tips guys.
As for converting to counter rotating props, it felt like it had a little more speed but I didn't notice any other difference in it really. Turns may be a little smoother but that might have more to do with fixing the tail boom
I was flying in 1mph wind this morning, as calm as it gets really, and I was still able to float in on landing with no power, what a great plane! (V1 from HK)
